  2. Olfactory nerve - Wikipedia

    en.wikipedia.org/wiki/Olfactory_nerve

    The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity.The olfactory nerves consist of a collection of many sensory nerve fibers that extend from the olfactory epithelium to the olfactory bulb, passing through the many openings of the cribriform plate, a sieve-like structure of the ethmoid bone.

  3. Sensory nervous system - Wikipedia

    en.wikipedia.org/wiki/Sensory_nervous_system

    Unique to the olfactory and gustatory systems, at least in mammals, is the implementation of both peripheral and central mechanisms of action. [ clarification needed ] The peripheral mechanisms involve olfactory receptor neurons which transduce a chemical signal along the olfactory nerve , which terminates in the olfactory bulb .

  4. Glomerulus (olfaction) - Wikipedia

    en.wikipedia.org/wiki/Glomerulus_(olfaction)

    Each glomerulus is composed of two compartments, the olfactory nerve zone and the non-olfactory nerve zone. The olfactory nerve zone is composed of preterminals and terminals of the olfactory nerve and is where the olfactory receptor cells make synapses on their targets. [2] The non-olfactory nerve zone is composed of the dendritic processes of ...

  5. Olfactory system - Wikipedia

    en.wikipedia.org/wiki/Olfactory_system

    The peripheral olfactory system consists mainly of the nostrils, ethmoid bone, nasal cavity, and the olfactory epithelium (layers of thin tissue covered in mucus that line the nasal cavity). The primary components of the layers of epithelial tissue are the mucous membranes, olfactory glands, olfactory neurons, and nerve fibers of the olfactory ...

    A 242A1 locomotive and standard gauge track at some model railway scales. This page lists the most relevant model railway scale standards in the world. Most standards are regional, but some have followers in other parts of the world outside their native region, most notably NEM and NMRA.

  7. Olfactory receptor neuron - Wikipedia

    en.wikipedia.org/wiki/Olfactory_receptor_neuron

    The axons of OSNs expressing the same odorant receptors converge onto the same glomerulus at the olfactory bulb, allowing for the organization of olfactory information. An olfactory receptor neuron (ORN), also called an olfactory sensory neuron (OSN), is a sensory neuron within the olfactory system .

  8. Olfactory bulb - Wikipedia

    en.wikipedia.org/wiki/Olfactory_bulb

    The olfactory bulb (Latin: bulbus olfactorius) is a neural structure of the vertebrate forebrain involved in olfaction, the sense of smell. It sends olfactory information to be further processed in the amygdala, the orbitofrontal cortex (OFC) and the hippocampus where it plays a role in emotion, memory and learning.

  9. Sensory processing - Wikipedia

    en.wikipedia.org/wiki/Sensory_processing

    Sensory processing is the process that organizes and distinguishes sensation (sensory information) from one's own body and the environment, thus making it possible to use the body effectively within the environment.
